LOCK-LATCH.

Specification of Letters Patent.

Patented Got. 23, 1917.

Application filed February 13, 1917. Serial No. 148,352.

To all whom it may. concern Be it known that I, Enosmr Paoon'r'rn, acitizen of the United States, residing at l-lolyoke, in thecounty ofHampden and State of Massachusetts, have invented new and usefulImprovements in Lock-Latches, of which the following is a specification.

This invention relates to lock latches.

The object of the present invention is to provide asimple inexpensivelatch for the attachment to sidewall: receptacles and the like, for thepurpose of preventing the un authorized raising, of the lid or closureof the said receptacle and the removal of the contents.

Another object of the invention is the pro vision of a latch of theabove description which is adapted to be placed on the bottom of areceptacle so as to be out of the sight of persons unfamiliar with thesame and to be locked in a manner to prevent its operation, the lockingmeans consisting of a pin inserted through the latch and the attachingplate in a manner to permit of its ready insertion and removal.

With these and other objects in view the invention consists of anattaching plate pro vided with a slot and a plurality of openingsintersecting the said slot, a spring controlled latch member mounted inthe slot upon a pivot provided in one of the intersecting openings, apin adapted to be inserted in the other opening and passed through anopening formed inthe latch member for locking the same againstindependent movement and a spring keeper arm adapted to be swung intothe path of the said latch member, said keeper arm being provided with anotch for engagement with a hook formed on the end of the latch member.

In the drawings;

Figure 1 is a sectional view of the receptacle having the. inventionapplied thereto;

Fig. 2 is an enlarged detailed sectional view on the line 2-2 of Fig. 1;

Fig. 3 is an enlarged perspective view of the latch removed from thereceptacle;

Fig. 4 is a detailed perspective view of the latch member;

Fig. 5 is a similar view of the keeper arm; and

Fig. 6 is a view of the locking pin.

Referring in detail to the drawings, the receptacle to which theinvention is shown applied is indicated at A. This receptacle is in theform of a show case such as is commonly sed by streetlvenders or thelike for the inspection of their goods. It includes the hinged closureB, which is of framed glass and the bottom (3, which is usually solid.The receptacle is adapted to be placed upon a suitable support D, theforward edge of the same projecting slightly over the receptacle so asnot to interfere with the latch.

-The latch comprises an attaching plate 10 which is adapted to besecured to the underside of the receptacles by means of screws or otherfastening devices 11. This plate is provided with a slot 12 and withopenings 13 and 14, which intersect said slot. These openings extendentirely across the plate and the opening 13 is adapted to receive apivot pin 15 by means of which the latch member 16 is pivoted Within theslot 12, the said member being provided with an opening 17 for thispurpose. In addition to the opening 17 the latch member is provided withan opening 18 which is adapted to be brought into register with theopening 14, for the passage of a locking pin 19, by means of which thelatch member 16 is locked against movement upon this pivot. Theattaching plate 10 is provided with a pin 20 and connected with this pinat one end, and to the latch member 16 at the other end, is a coiledspring 21, by means of which the said latch member is controlled.

Secured to the bottom edge of the hinged closure 18 is a spring keeperarm 22, this keeper arm being secured to the closure by means of apin23, this pin also being employed to secure a finger piece 24 to theout side of the closure for the purpose of operating the same. The freeend of the spring keeper arm 22 is formed with a notch 25 and with abeveled portion 26. When the closure 1) is swung into a closed positionthe beveled portion 26 of the arm 22 will engage the beveled notchedportion 27 formed in the latch member 16, the said notched portionproviding a hook 28 on the said member for engagement with the said arm.In order to release the latch member from engagement it is necessary toswing the hook member 16 upon its pivot, which permits the raising ofthe closure B. By inserting the locking pin 19 through the open ings 14and 18 this action is prevented.

As will be seen from Fig. 1 the latch is located beneath the receptacleand out of the view of passers by and in order to raise the lid orclosure, 18 for the purpose of re moving the contents from thereceptacle it is necessary to reach beneath the same and remove thelocking pin l9before the latch can be operated. When the latch is notdesigned to securely locl: will torm a suilicient safeguard to preventits operation by unauthorized persons.

Having described the invention, that is claimed is:

l. A lock latch comprising an attaching plate provided with a slot, aplurality of openings intersecting said slot, a spring controlled latchmember pivoted Within said slot, a spring keeper arm adapted to bebrought into the path of the said latch member, a pivot provided in oneof the intersecting openings for the mounting of the latch member and aremovable pin adapted to be inserted in the other opening and passedthrough an opening in the said latch the receptacle, it 7 a receptacle alock latch therefor, said latch comprising an at;

taching plate provided With a slot and a plurality of openingsintersecting said slot a spring controlled latch member pivoted in saidslot, a spring keeper arm located in the path of the said latch member,a pivot provided in one of the intersecting openings tor the mounting ofthe latch member and a removable pin adapted to be inserted in the otheropening and passed through an opening in the said latch member for lock-I ing the same against independent movement.

In testimony whereof I aihx my s1gnature.
